SIGRIST-PHOTOMETER AG at Swiss Tunnel Congress in Lucerne

From June 10 to 12 the latest Swiss Tunnel Congress took place in Lucerne. Over 750 participants of totally 14 countries received an in-depth view of the capabilities of the Swiss tunnel industry. A series of technical presentations, excursions to current tunnel construction sites as well as an exhibition created a valuable meeting point for the industry audience.

The FireGuard measures the scattered light intensity in tunnels with scattering angle, measuring range, response threshold and signal processing being optimized for smoke and fire detection. Air sample is fed through the measuring cell without the use of a fan, effectively preventing from window soiling. Calibration is performed in E/m and can be checked easily with a calibration rod.

VisGuard Extractive

The VisGuard measures the scattered light intensity of a sample drawn into the instrument. Filtered purge air is fed through the flow cell, thus enveloping the sample in a protective shroud of clean air. This effectively keeps the optics clean. Installations are either in the tunnel cavity/niches (in-situ) respectively using extractive sampling away from the cavity. An optional sample heater eliminates the influence of any mist effects.

Secure File Exchange

Secure File Exchange (SFX) is used to exchange files with SIGRIST. The web-based tool allows the exchange of many files, or files that are very large. On request, the transmission is encrypted and thus only accessible to authorized recipients.

With SFX you upload the files to a bucket. The web address of this bucket can then be shared with the recipient. If you set a password, the bucket is encrypted. If you do not set a password, then the bucket is not encrypted and is accessible to everyone who is in possession of the web address.
